What do pipettes measure?

Pipettes measure and transfer small amounts of liquid with high precision. They are used to accurately measure and dispense volumes ranging from microliters to milliliters, depending on the type of pipette. Pipettes are calibrated to ensure accurate volume transfer, which is crucial for experiments in chemistry, biology, medicine, and other scientific fields. They measure liquid volumes by the position of the liquid meniscus within the graduated marks on the pipette, or in the case of electronic pipettes, they automatically measure and dispense liquid based on preset volumes.
